ESTIMATING IRRATIONAL NUMBERS - onlinemath4all
Square roots of perfect squares are rational numbers. Square roots of numbers that are not perfect squares are irrational. The number √3 is irrational because 3 is not a perfect square of any rational number. Estimate the value of √2 A. Since 2 is not a perfect square, √2 is irrational. B. To estimate √2 , first find two consecutive perfect squares that 2 is between.
